ABSTRACT This research draws on the model of positive play (i.e. responsible gambling) to investigate whether positive play beliefs (e.g. accurate understanding about the odds of success on games of chance) and behavior (e.g. setting a limit on gambling expenditures) are associated with attitudinal loyalty and behavioral loyalty. Results from Study 1 indicated that among American casino loyalty program members (N = 188), positive play was predictive of attitudinal loyalty when controlling for disordered gambling symptomatology. In Study 2, using survey and player-account data from 383 members of a Canadian casino loyalty program, we found that positive play was negatively associated with behavioral loyalty, but that this association was eliminated after accounting for disordered gambling symptomatology. These results suggest that fostering positive play may help increase positive perceptions of a casino and its loyalty program without undermining the amount of money a player spends at that casino.
